What are those odd green fruits that look like they’re covered in scales? Not dragon fruit, ironically, but cherimoyas. Native to South America, these tropical fruits have a mild, sweet flavor like banana-pineapple custard. They should appear in markets beginning now and lasting through April or May, making for a nice alternative to the ubiquitous winter citrus. Pick out the large black seeds and puree the interior to make fragrant sorbet or granita. Or try adding cherimoya to a smoothie with avocado and mint for a green surprise.
